In other words, the pressure of a gas is inversely proportionate to the volume of the gas provided the temperature is constant
provided the amount of gas is the same]]> 2016-10-31 00:25:14 UTC https://padlet.com/ronaldoyee_161/ek2avrtvhulv/wish/134120758 ronaldoyee_161 https://padlet.com/ronaldoyee_161/ek2avrtvhulv/wish/134121403 When the temperature of a gas increase, it's volume will increase. i.e. as a gas is heated, it will expand.

The marshmallow will expand. This is because as the air is being removed from the jar, the pressure in the jar decreases, causing the pressure in the marshmallow to also decrease as well to cope with the pressure difference which cause the marshmallow to expand.
A balloon is placed in a bell jar and air is extracted from the bell jar. The balloon will expand because the the pressure in the bell jar decrease.]]> 2016-10-31 00:52:04 UTC https://padlet.com/ronaldoyee_161/ek2avrtvhulv/wish/134122646 ronaldoyee_161 https://padlet.com/ronaldoyee_161/ek2avrtvhulv/wish/134676284 When you put the mouth of an uninflated balloon onto the mouth of a bottle and heat up the bottle, the balloon will inflate because the temperature of the air in the bottle increase, causing its volume to increase as well
A deformed ping pong ball placed into a tub of hot water will regain its original shape because the air inside the ping pong ball heats up, causing it to expand.
To inflate a hot air balloon, you should introduce heat to the mouth of the balloon. This will heat up the air in the balloon and will cause it to inflate.]]> 2016-11-02 05:21:44 UTC https://padlet.com/ronaldoyee_161/ek2avrtvhulv/wish/134676284 ronaldoyee_161 https://padlet.com/ronaldoyee_161/ek2avrtvhulv/wish/134676433 The pressure in a bicycle tyre will increase from night to mid-day due to a change in temperature.

When you pump air into the  space above the water, the water will flow out because the pressure in the bottle increase, causing the water to flow out from the bottle.]]> 2016-11-09 10:57:53 UTC https://padlet.com/ronaldoyee_161/ek2avrtvhulv/wish/136345235
